Este trabalho teve como objetivo, estudar a frequência do grau de risco de ocorrência de queimada e de incêndio e as medidas de prevenção, em Belém - PA, no ano de 2015, a fim de contribuir com os sistemas de alertas, na divulgação do controle do fogo, pois causam custos e degradação ambiental e são fatores negativos para as sociedades. Foram utilizadas as temperaturas do ar, umidade relativa e a precipitação, dados das 15: 00horas locais, obtidos no Instituto Nacional de Meteorologia. Os índices de predição foram o Fator de Risco de Angstrom (FRA), Fórmula de Monte Alegre (FMA) e o Índice de Nesterov (IN). O clima de Belém-PA, no ano de 2015, mostrou que, o regime de temperatura do ar é estável, o déficit de pressão do vapor d’água apresenta conteúdo significativo de vapor d’água, a umidade do ar é elevada e a precipitação pluviométrica nos trópicos assume papel preponderante. O índice FRA apresentou valores mais elevados quando comparados aos valores de FMA e IN, com resultados confluentes. Os modelos FMA e IN apresentam forte correlação positiva e entre o índice FRA, boa correlação positiva nos resultados. Belém–PA, com a falta de chuvas, apresenta valores mais elevados, nos graus de grande risco (GR) e de altíssimo risco (ALR) e a prevenção é de fiscalização intensa e redobrada (FIR) e de estado de alerta (EA) e com a volta da estação mais chuvosa, o risco de ocorrência cai drasticamente, com as maiores frequências nos graus de nenhum risco (NR) na região.

This research aimed to study the frequency of occurrence risk level of burning and fire and prevention measures in Belém-Pará-Brazil, in the year of 2015, in order to contribute to alert systems, in fire control divulgation, because are negative factors for society and causing costs and environmental degradation. Were used air temperatures, relative humidity and precipitation data from the 15:00 local time, obtained from the National Institute of Meteorology. The prediction indexes used were: Angstrom Risk Factor (FRA), Monte Alegre Formula (FMA) and Nesterov Index (IN). The climate of Belém, in 2015, showed that the air temperature pattern is stable, the water vapor pressure deficit has a significant content of water vapor, high air humidity and the rainfall in the tropics takes leading role. The FRA index presented higher values compared to the values of FMA and IN, with confluent results. The FMA and IN models demonstrate consistent positive correlation, and between the FRA index, good positive correlation in the results. The city of Belém, with the lack of rain, shows higher values in degrees of high risk (GR) and very high risk (ALR) and the prevention measure is of intense and redoubled inspection (FIR) and alert condition (EA) and with the return of more rainy season, the risk drops dramatically with the highest frequencies in the degree of any risk (NR) in the region.
Keywords: Fire and burning risk, preventive measures, risk indices, meteorological elements, Belém-Pará-Brazil.
